JSW Steel Interview Questions, Process, and Tips

Before starting erection activities, it is important to check for safety hazards, proper equipment, and necessary permits.

• Ensure all safety hazards are identified and addressed

• Check that all necessary equipment is in working order

• Verify that all required permits and approvals are obtained

• Inspect the site for any potential obstacles or obstructions

The selection of a crane depends on factors such as weight capacity, reach, height, and terrain.

• Consider the weight capacity of the crane to ensure it can lift the required loads.

• Evaluate the reach and height of the crane to determine if it can access the work area effectively.

• Take into account the terrain where the crane will be operating to choose the appropriate type (e.g. rough terrain crane, crawler crane).

Load angle factor is a term used in engineering to describe the angle at which a load is applied to a structure.

• Load angle factor is important in determining the stress and strain on a structure.

• It is typically calculated by taking the cosine of the angle at which the load is applied.

• For example, if a load is applied at a 45 degree angle, the load angle factor would be cos(45) = 0.707.

Sling angle factor refers to the angle at which a sling is attached to a load, affecting the load's stability and the force exerted on the sling.

• Sling angle factor is calculated by dividing the actual load weight by the weight of the load being lifted.

• A smaller sling angle increases the force on the sling and decreases its capacity.

• A larger sling angle reduces the force on the sling and increases its capacity.

• Proper ca...read more

Safe load lifting percentage refers to the maximum weight a person can safely lift based on their capabilities.

• Safe load lifting percentage is typically calculated as a percentage of a person's maximum lifting capacity.

• Factors such as age, gender, fitness level, and previous injuries can affect safe load lifting percentage.

• It is important for employees to be trained on proper lifting techniques to prevent injuries.

• For ...read more

HIRA stands for Hazard Identification and Risk Assessment. It is a process used to identify potential hazards and analyze the associated risks in a workplace.

• HIRA involves identifying hazards that could cause harm, assessing the risks associated with those hazards, and implementing control measures to mitigate the risks.

• Examples of hazards include chemical exposure, machinery malfunctions, and ergonomic issues.

• The goal...read more

MCB is a miniature circuit breaker, ELCB is an earth leakage circuit breaker, and RCCB is a residual current circuit breaker.

• MCB is used to protect electrical circuits from overloads and short circuits.

• ELCB is used to detect earth faults and disconnect the power supply to prevent electric shocks.

• RCCB is used to detect residual current imbalances and disconnect the circuit to prevent electric shocks.

• MCB and RCCB are com...read more

To check the Crane girder Camber, measurements can be taken using a straight edge or laser level.

• Use a straight edge to measure the camber of the crane girder by placing it along the length of the girder and checking for any deviations from a straight line.

• Alternatively, a laser level can be used to project a straight line along the length of the girder and measure any deviations from this line.

• Regular inspections shou...read more

Luffing jib moves vertically to change the angle of the hook, while fly jib extends horizontally to increase reach.

• Luffing jib is used to change the angle of the hook without moving the crane itself.

• Fly jib extends horizontally to increase the reach of the crane.

• Luffing jib moves vertically, while fly jib moves horizontally.

• Luffing jib is commonly used in high-rise construction projects, while fly jib is used for reach...read more

Motor starters with contactors provide protection by controlling the electrical supply to the motor.

• Motor starters with contactors prevent overload by disconnecting the motor from the power supply when excessive current is detected.

• They also protect against short circuits by quickly interrupting the circuit in case of a fault.

• Thermal overload relays can be used in conjunction with contactors to provide additional prote...read more

P2P cycle involves the entire procurement process from requisition to payment.

• Requisition: Request for goods or services

• Approval: Authorization of requisition by appropriate personnel

• Purchase Order: Formal document to supplier for goods/services

• Receipt: Verification of goods/services received

• Invoice: Billing from supplier

• Payment: Settlement of invoice
